The ls(1) command has a lot of options (Look at the man page synopsis!). So much so, that the most recent option added in DragonFly is “_”. That’s to show nanotime as part of the -l output. This will be most useful when you have multiple files being created within the same second of time, and you want to see which came first.
Almost all of this was done within 24 hours of the last Lazy Reading. No idea why there were so many good candidates for reading, but I’m happy about it.

I’m still catching up with the pre-2018, pre-Meltdown commits, so here’s one: Changing the staged packet count in DragonFly changes forwarding rate, for the better – up to a point. There’s probably some specific ratio in the change that makes sense, though I don’t know it.
The commands rcp(1), rlogin(1), rlogind(1), rsh(1) and rshd(1) have been removed from DragonFly. There’s a net/bsdrcmds port if you still need them… though I imagine/hope ssh is filling the void for everyone.
I say “one more” like I know when this saga will end. If you are using the devcpu-data port to update your processors, you’ll need to add
to your /etc/rc.conf, as Sepherosa Ziehau points out.
This is almost all link overflow from last week – and next week’s edition is almost complete. There’s a lot to read lately!

The regular maintenance scripts for HAMMER1 assume that it’s mounted at the time of cleanup. If you have them unmounted, they won’t go through that regular maintenance, but it’s easy enough to fix.
Matthew Dillon posted a summary of IBRS and IBPB support in DragonFly, and some numbers showing its impact in various configurations of options and CPUs.
Are you tired of hearing about Meltdown/Spectre yet? Doesn’t matter! The two sysctls for controlling mitigation in DragonFly have been renamed:
They go to hopefully sensible defaults, but Matthew Dillon has done some testing to show the effects of each in various combinations. (Update: more changes and tests.) Note that this is not the final mitigation work; compilers (i.e. gcc) are being updated to include workarounds for this, so new gcc -> new compiler in DragonFly -> new defenses. No silver bullet there, though.
One side effect of Meltdown/Spectre are CPU microcode (firmware) updates. For future needs: sysutils/devcpu-data is the port that has the updates for Intel, and cpucontrol(8) is the program you run on DragonFly to add them.
I haven’t used this myself, yet, so I can’t tell you how necessary an immediate update could be – but you will probably want to use it soon.
Update: Newer CPUs might require this sizing change.
I had to trim this down; there’s been a post-Christmas surge in material.
